Introductory notes: <ul>
<li>
In Fortran code, GSL_* must be replaced by FGSL_* for each API call, abstract data type, module variables and parameters (with exception of the M_* mathematical constants) </li>
<li>
Some names were changed due to UC/LC aliasing. See the documentation chapter on special functions for details. </li>
<li>
Intrinsic type matching:<ol type="1">
<li>real(fgsl_double) is used for double precision values</li>
<li>real(fgsl_float) is used for single precision values</li>
<li>integer(fgsl_int) for integer</li>
<li>integer(fgsl_long) for long integer</li>
<li>integer(fgsl_size_t) for size_t integer</li>
<li>complex(fgsl_double_complex) for <a class="el" href="structfgsl_1_1gsl__complex.html">gsl_complex</a></li>
<li>character(fgsl_char) for characters</li>
<li>no value attributes and mostly no pointers in Fortran calls</li>
<li>unsigned int must be converted to integer(fgsl_long).</li>
<li>char * results are converted to fixed length strings. Use TRIM. </li>
</ol>
</li>
</ul>
</li>
<li>
Additional routines: <ul>
<li>
Generic interface <a class="el" href="interfacefgsl__well__defined.html">fgsl_well_defined</a> for checking status of FGSL objects (which are typically opaque). </li>
<li>
See <a class="el" href="array_8finc.html">api/array.finc</a> for array alignment routines. </li>
<li>
See <a class="el" href="math_8finc.html">api/math.finc</a> for function object constructors. </li>
<li>
See <a class="el" href="io_8finc.html">api/io.finc</a> for I/O related add-ons. </li>
</ul>
</li>
<li>
Structure of the documentation: <ul>
<li>
type definitions are in the fgsl section of the Modules menu item </li>
<li>
all API routines are available via the Files menu item </li>
<li>
additional remarks on the various files are available via the Related Pages menu item </li>
</ul>
</li>
<li>
Only interfaces from the GSL manual are implemented. The C include files may contain more stuff which may only be meant for internal use, or is not officially documented. </li>
<li>
Inlining of GSL routines is not possible. </li>
<li>
Macros are not supported: <ul>
<li>
macro values are replicated as parameters </li>
<li>
Inf/Nan need to use IEEE_VALUE (if available) </li>
</ul>
</li>
</ol>
